T0 all A107mm it may 'concern Be it known that I, EDWARD F. BrinesTRoM, a citizen of Sweden, residing at Walthaln,in the county of Middlesex and State of Massachusetts, have invented certain new and useful improvements in Fnvelops, of which the following is a specification.

This invention has reference to improvements in envelops, and its object is to provide an envelop, and more particularly a return envelop, which may have the secrecy of an ordinary sealed envelop without-liability of surreptitious access toits contents, and which, moreover, may be readily constructed in a manner to provide a safety receptacle for money, whether in the form of coin or hills.

ln accordance with the present invention there is provided a sheet which may be folded into the form of an envelop capable of being completely sealed, or, if desired, simply closed without sealing, and the recipient of a communication inclosed in the envelop may, by the removal of the used yaddress portion. reuse the envelopfor return to the sender, for whichpurpose the senders name may or may not be prewritten or printed upon the return address side.

The present invention is particularly adapted for the sending of money in the form of coin or bills, since by a slight change in the form of the envelop a coin pocket is provided whichl may be sealed` against surreptitious removal of the coin and the sealing may be multiplied without, however, preventing 'the recipient from readily removing the coin, andif need be, utilizing the coin pocket for the reception of some other matter and the recipient may use the same envelop for inclosing a reply to the communication, and in case the matter inclosed in the return envelop permits, the latter may be utilized in the closed but unsealed condition, thus saving postage. However, if the reply be such as to demand letter postage then the reply part of the envelop may be readily securely sea-led.

rThe envelop ofthe present invention is particularly adapted for economical production and the utilization of a minimum, amount of material,

.The invention will be b est understood freni as consideration of the following detailed' description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that while the drawings show a practical :form of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified, so long as f such changes and modifications mark no material Specification. of Letters 'JPatent Patientin@ tpm 313,' Application led January 17,1914.

Near that edge 'of' the-main portion 1 remoteffrom the 'flap 5 elongated slot 11 of a length to receive the tongue 6, and this slot is spaced an appropriate distance from the adjacent edge of the main portion 1, which 1n an envelop of ordinary size is about onehalf inch, but this vdistance is not at all obligatory.

' In preparing the envelop for use the extensions and 4are folded overon to the main portion 1 on the lines 12 and 13, re-

The end flap 2 isfold'ed onto the main portion 1 along the dotted line of fold indicated at 14, the strips 7 of the adhesive having been suitably moistened, or as is usually the casel in the manufacture the folding may-be done While the -adhesive is still moist, whereupon there is formed an envelop with a receiving portion parts l and 2 closed on three sides determined by the integral connection at 14, and the adhesion of the flap 2 to the folded-over strips 3 and 4. That face of the yflap 2 remote from the observer in the showing of F ig.` 1 is designed to receive the secondary or return address and is shown at 2a in Fig. 5. That portion ofthe flat 5 which is remote from the observer in Fig'. l is designed to receive the primary address and is shown at 5a in Fig. 3.

'The only part of theenvelo' not-employed for return purposes is -t e portion of the Hap 5 beyond the tear-oil' line 10, and the tongue 6. The structure is a-simple one if with tthe rey--place'd' upon employing'a minimum amount of'paper, and

providing a securely sealed envelop especially where privacy is demanded, and, moreover,'the interior of the envelop maybe of the full Size of the body of the-envelop, and this is true whether the the initial sending or for return purposes-` In Fig. 7 shown permitting the use of the-envelop either for the initial sending or for return purposes in either the sealed or unsealed condition. For this purpose the blank comprises a body portion 17 which in the particular form shown is shapedas an elongated-rectangle after the manner vof ordinary business envelops, but which may be otherwise shaped as desired. At the ends of the envelop are flap extensions- 18,. 19, 'respectively, ofsimilar shape, and each a little longer than half the length of the body portion 17. At the long sides tion are flaps 20, 21, respectively, each pro,-

loe

and Athe en VVA envelop be used for of the body porf tamtam@ vided vat the .edge remote from the body of the envelop with a tongue 22, 23, respectively. Along one long side of each flap 18 and 19 is a strip 24 of adhesive, and along the free end of the flap 18 is a strip 25 of adhesive, while each tongue 22, 23 has at the free end a strip 26 of adhesive. 'lhe body portion 17 near the respective flaps 20 and 21 is provided with elongated slots'27, 28, respectively. rlhe daps 18 and 19 are wider than the effective height of the 4body portion 17 by the width of that part of each flap covered by the strip 24 of adhesive. New., when the envelop in Fig. 7 is assembled the 4strip 24 of the dap 19 is moistened and the flap is bent on the line 29 where it joins the body portion 17 on to said body portion with the adhesive 24 against the corresponding portion of the dap 21, so that the Hap 19 is joined to the Hap 21 along said part. rllhen the flap 18 with the adhesive moistened is folded on the line 30 over the body portion 17 with the adhesive 24 engaging and adhering to the portion of the flap 19 on the face thereof remote from the adhesive 24 and the adhesive 25 connects the flap 18 along the corresponding edge to the like edge portion of the flap 19 on the face remote from the body portion 17. 'lhis provides the usual envelop receiving part but with the flap 21 extending therefrom, and this flap, as well as the portions of the flaps 18, 19, provided with the adhesive 24 are folded on the line 31 against the daps 18, 19,

while the tongue 23 with the adhesive 26- thereon unrnoistened or dry is folded against the flap 21 on the junction line 32'. That face of the flap 21 away from the observer in Fig. '7 and indicated at 21";L in Fig. 8 provides space for the return address. 'llhe dap 20 is folded on the line 33 over the address face of the flap 21 and the tongue 22 is folded on the line 34 around the line of fold 31, whereupon the tongue 22 maybe inserted through the slot 28 if the envelop is to be sent unsealed, or the adhesive 26 is moistened and the tongue 22 is made to adhere to that face of the body portion 17 remote from the observer in Fig. 7. 'lhe first address is applied to the face of the flap 20 remote from the observer in Figs. 7 and 8 and indicatedat 20a in Fig. 9.

When the recipient of the envelop desires to gain access thereto "the tongue 22 may be severed at the line 34 or the Hap 20 may be severed at the line 33, or the parts may be severed at both lines. r1`his gives free access to the interior of the envelop and also releases the dap 21 with its tongue 23 and, moreover, exposes the face 21a of the flap 21 which may have the return address already thereon, and if not, provides a space for the return address. Now, the return communication or whatever it is desired to place in the envelop may be inserted therein and' the Hap 21 is so placed that its tongue 23 may be folded on the line 32 about the then exposed edge 33 along which the-flap 20 has been severed, but in case the Hap 20 is not removed along the line 33 said Hap is turned down against the united flaps 18 and 19 and is then covered by the dap -21 with the return address exposed and the tongue 23s is passed around the edge 33 and either inserted in the slot 27 or sealed against the corresponding face of the body portion 17 after the adhesive 26 of the tongue 23 has been moistened.

1n either form of envelop the amount of paper employed exceeds to only a fractional extent that used in the ordinary business envelop, so that there is provided a return envelop at a cost of production but little above that of an envelop capable of use in but one direction, and far less than the cost of two envelops which it would be necessary to use. Moreover, in the forms shown in Figs. 1 to 9 the mucilage or adhesive is applliendk throughout to the same face of the dt but slightly additional expense because requiring a small additional amount of paper, the envelop may be provided with an additional receptacle which can be utilized for money either in the form of coins or bills, or, if desired, may be employed for the reception of postage stamps or other medium of exchange. @ne suchform of return envelop having a coin receptacle is shown in Figs. 10 to 14 where there is provided a body portion 35, which like the other envelops may be of elongated rectangular shape, though not confined to such shape, and at the end of the body portion are flaps 36, 37, similar to the flaps 18 and 19 except that they are more elongated so as to overlap for an appropriate distance. Considering the flap 36 as the one first folded toward the body portion 35, the flap 37 is provided at joints indicated at 38 and 39 with bands of adhesive, so that the two flaps may be united at spaced points to form a pocket 40 best shown in Figs. 12 and 13, but indicated in Fig. 10. Une of the iiaps, the flap 36 in the showing of Fig. 10, is provided with a widened portion 41 forming a tongue which may be folded down over the mouth portion 42 of the pocket 40, and this tongue has the appropriate face covered with adhesive 43, so that it may be cemented to the flap 37 where it comes in contact therewith, thus closing the coin pocket or receptacle. The height of the flaps 36 and 37 may be reduced where they overlap to provide for the flap 41 without the latter extending beyond the margins of the body portion 35. rFhere are also provided flaps 44 and 45 corresponding to the flaps 20 and 21 of the form shown in Fig.

' 48 of adhesive, as in Fig. 7. The -faces of the joined flaps 36`and 37 in Fig. 10, and

value 1s sending-of money or other means of eX the coin or other representative of change,

placed in the joined portions of the flaps 36 and L37 and y the tongue 41 is sealed down over the mouth Tis of the coin pocket. Now the flap 45 with the tongue 47 folded'down against 1t is folded against the connected flaps 36 and 37 and the flap 44 is folded on a line 49 over the then outer face `of the flap 45 and since the envelop contains money or other form of exchange the tongue 46 is sealed against the outer face of the body portion' 35 and that face of the flap 44 remote from the observer in Fig. 10 and indicated at 44a in Fig. 13 is designed to receive the primary address. When -suoli an envelop is received by the addressee it may be opened by removing the tongue 46 along the line 50 and severing the tongue 41 Where it joins the permitting access to the pocket 4() and the la'p 36, thus removal of the coin or other value therein indicated at 51 in Figs. 10 and 13.

l l the flap-45 is If it be assumed that some form of merchandise is to be returned in the envelop,

then the flap 44 if it has not already been removed along the line 49 may be folded down against the joined flaps 36 and 37 and folded up against the flap 44 or in the event of its absence, against the joined flaps 36 and 37 with the tongue 47 extended about the edge 49 and the tongue 48 introduced through a slot 52 similar to the slot 27 of the form shown in Fig. 7, this arrangement of parts being shown in Fig.

:14, which represents a cross section of the envelop after the Hap 44 has been removed. It Will be understood, of course, that in case the envelop is to be sealed the'tongue 47 is cemented to the outer face of the body portion 35 by means of the adhesive 48. :That face of the flap remote from the observer in Fig. 10 and indicated at 45a in Figs.` 13 and 14, provides a space for the return address. Another form of return envelop with a coin receptacle is shown in Figs. 15 to 18, and in some respects corresponds to the showing of Fig. 10 and associated figures. There is a blank having a body portion 52a indicated as of elongated rectangular form following the usual practice in business envelops, but which may be otherwisefsliaped, and 'this body. portion has end fla-ps 53, 54, each in part higher than the body'portion L52, but with what const-itutes the upper edge cut down for a portion of the length and,

pocketv formed bythe vmay be placed in that provided with respective upstanding tongues 55, 56, the flap 54 adjacent to the junction line of the tongue 56 therewith being provided with an elongated slot 57, While that face of the tongue 56 toward the observer iii Fig. 15 has adhesive 58 applied thereto. On opposite sides of the body portion 52 are respective flaps 59 and 60, -those parts of the flaps 53 and 54 which may be termed their lower edges in Fig. 15 extending for a short distance along the lines of the fiap 60 and there are provided with adhesive 61. That end of the flap 54 remote from the body ortion 52a has a band 62 of adhesive app ied thereto, and in spaced relation to the adhe` sive 62 and on the side of the tongue 56 toward the body portion 52a the flap 54 'has another band 63 of fadhesive substantially parallel with the band 62. Along the three free edges of the fla 60 is a band 64 of ad` hesive. The flap 59 as a tongue 65 projecting therefrom on the side remote from the point of union with the body portion 52= and this tongue has its terminal portion provided With a band 66 of adhesive, While the flap 59 at an appropriate distance from its line of junction with the body portion 52 has produced therein a line 66 of indentations or perforations for tearing or severing purposes. The body portion 52l1 tance from the iap 60 has an 67 produced therethrough.

The envelop of Fig. 15 is assembled by folding the flap 53 on to the body portion 52a along the line 68 and hesive 61 to adhere to the corresponding portion of the flap 60. Now, the iap 54 is folded against the flap 53 along the line 69 and joined thereto by* the bands 61,' 62 and 63 of adhesive'with the tongue 56 joined to the tongue by the adhesive 58. This produces a closed coin pocket except for the slot 57. The iap and the parts of the flaps 53 and 54 fast thereto may now be foldedon the Alinev 70 until against the main body of the flaps 53 and 54, but without any elongated slot adherence ofthe band 64 of adhesive with the parts it engages. The envelop may now receive money through the slot 57 into the coin pocket and any desired communication part of the envelop between the flaps 53 and 54 and the body portion 52 or the exposed faces of the iaps 53 and 54 may be utilized for any communi- 'cation and may contain printed matter, as indicated in Fig.- 16.4 Now the flap 59 is folded alon the line 71 into covering relation to the ap 60 and in the event of money being carried by the envelop the tongue 65 is sealed against that face of the body portion 52 remote from that observed in Fig. 15.

If it is not necessaryto seal the envelop then the tongue' 55 may be introduced through at a short dis- 1 causing the adthejslot 67 vvithout permanently sealing the envelop. When the addressee receives the lll instaan Y envelop the Hap 59- may be removed along the line 66 or the tongue 65 may-be severe trom the Hap as in the other torms provided the envelop be sealed by the tongue 65.

ylUttliervvise the tongue .65 may simply be removed from the slot 67 andthe envelop be opened. lin order to reach the coin the two joined tongues and 56 are torn od' at the slot 57, thus opening the coin pocket and the money may then be removed. 'llo return material in the envelop the tlap 59 is torn od' along the line 66 and after the material has been introduced into the envelop the adliesive 6d is moistened and the tlap.60 is sealed along the Vlong side and the edges 'against the corresponding portions of the daps\.53 and 54 andA along that portion of the Hap 59 still remaining attached to the envelop, such portion being turned down against the flaps 53 and 54 along the line 71,

so that the Whole envelop is thoroughly' sealed at all points.

lin the form of envelop shown in Fig. 15 and associated figures the adhesive is applied at all points to the same side of the blank, but in the form shown in Fig. 10 and associated figures the adhesive applied to the dap d1 is applied to the opposite face of the blank :trom the other lines of adhesive.

lln the di-tlerent forms of envelops shown and'described the tongues 6, 22, 23, 46, 48'

and'65 are all shown substantially alike. lt is evident, however, that such tongues may be variously shaped, and in Figs. 19

tension 72 which may be covered on one side with adhesive 7 3f ln Fig. 20 there is shown lis l case may be, may Vary and the'slot designed to receive the tongue may be of a length to receive the extension 7 2 or 7 2a only, While the distance of the slot from that edge of the i envelop over which the tongue is folded is agreeable to the length of the tongue 65 or 65h from the flap to the respective extension. Furthermore, the extensions 72 or 72a may vary in length, but should be long enough in any instance to hold the flap in place when inserted through the proper slot. When it is desired to seal the tongue against the body ot the envelop the adhesive 7 3 or 73a is moistened and caused to adhere to the envelop without the tongue extension being passed through the slot.

From these examples it becomes apparent that the invention is not limited to the particular shapes and sizes indicated, but may be varied in these respects vvithinv vvide limits.
